JACOB G. ELKIN, OF NEW YORK, N. Y.

CONNEC'IING-CLIP FOR ELECTRICAL CONDUCTORS.

To all 'whom t may concern:

Be it known that I, JACOB G. ELKIN, a citizen of the United States, anda resident of the city of New York, borough of Manhattan, in the count-yand State ot New York, have invented a new and Improved Connecting-Clipfor Electrical Conductors, of which the following is a full, clear, andexact description.

'Ihe object of the invention is to provide a new and improved connectingclip for electrical conductors to permit the operator to securely:tasten the clip to insulating conductor wire, and to allow of the clipbeing conveniently and quickly attached to or detached from a bindingpost or the like.

In order to accomplish the desired result, use is made of a pair ofspring-pressed jaws pivotally connected with each other and adapted toengage a binding post or the like, a clamp held on the pivots of thejaws and adapted to engage the bare end of the wire conductor, and meansfor closing or opening the said clamp. Use is also made of a. piece ofrubber tubing inclosing the jaws except the heads'thereof, and pressingthe jaws inwardly toward each other to assist the spring of the jaws tohold the latter closed, the said piece of tubing also inclosing the saidclamp and closing means for the same and extending onto the insulationot the conducting wire.

A practical embodiment of the invention is represented in theaccompanying` drawings forming a part of this speciiication, in whichsimilar characters of reference indi cate corresponding parts in all theviews.

Figure l is a sectional plan view ot' the clip as applied; Fig. 2 is alongitudinal central section of the same; Fig. 3 is an invertedsectional plan view of the same; Fig. 4 is an enlarged cross sectionofthe same on the line 1 -1 of Fig. 2; Fig. 5 is a similar view of thesame on the line 55 of Fig. 2; and Fig. 6 is a cross section ot therubber tubing.

The jaws A and B of the connecting clip are provided with heads A', Badapted to clampingly engage a binding post C or the like, and theshanks A2, B2 of the jaws A and B are pivotally connected with eachother by a pivot D and are pressed toward each other by ay spring Ehaving its ends attached to the shanks A2, B2 of the jaws A and B. Theheads A' and B' of the jaws are arranged in the same plane and haveSpecification of Letters Patent.

their inner or opposite edges provided with recesses A2, B3 forengagement with the binding post C so as to insure a firm conduct withthe peripheral 'face of the binding post. The forward inner edges A4, B2of the heads A', B' are beveled in an outward direction so as to form anopen mouth for readily engaging the heads A', B' with the binding post Cwith a view to spread the heads A', B' apart against the tension of thespring E untilthe recesses A3, B3 engage the peripheral face of thebinding post C as plainly indicated in Fig. 1. In order to hold the jawsA and B in the same plane while opening and closing the jaws use is madeof a retainer F provided with forks F', F2 straddling the shanks A2, B2(see Fig. 5). The central bar F3 ot' the retainer F extends between theshanks A2, B2 and the latter are provided at their inner edges withrecesses A5, B5 in register with the central bar F3 so as to allow theheads A', B' to close completely, as indicated in Fig. 3.

The heels A, B6 of the shanks A2, B2 overlie one the other and areengaged by the pivot D so as to allow the jaws to swing laterally intoan open or ay closed position. On the pivot D is secured a clamp Grhaving clamping members Gr', G2 adapted to engage between them the bare.end H ot the insulated conducting wire H. The free ends of the clampingmembers G', G2 of the clamp G extend into the base end of a. conicalbore I formed centrally in a. bolt I screwing into an angular lug B7integrally formed on the rear end of the heel BG of the jaw B. The bareend H of the conducting wire H extends through the bore I' to finallypass between the clamping members G', Gr2 which are pressed in i'irmcontact with the said bare end H' on screwing the bolt I forwardly inthe lug B7. The rear end of the bolt I is provided with a head I2adapted to be taken hold of by the operator for screwing up the boltIwhenever it is desired to clamp the bare end H' in position between theclamping members Gr', Grt.v By the arrangement described a very firmconnection is had between the bare end H' of the conducting wire H andthe clip proper so as to insure a proper passage of the electricalenergy.

A tube J, of rubber or similar material, and preferably flat in crosssect-ion, as indicated in Fig. 6, is stretched over the Shanks A2, B2 soas to assist the spring E in pressing the jaws A and B toward eachother, and the said tube J also incloses the clamp G, the bolt. I andthe end portion of the insulation of the conducting wire II so that theseveral parts are well protected with the heads A and B only exposed atthe front end of the tube for making connection with the binding post C.

The co-nnecting clip forv the electrical con'- ductor shown anddescribed is very simple in construction and can be readily attached toor detached from a binding post C or the like, and the bare end H of theconducting wire can be quickly and securely attached to the clamp G heldon the clip proper.

rIhe tube J by bearing on the head I2 of the bolt I prevents accidentalturning of the bo-lt, and by the us-e of the tube J the clip can besafely handled with the full current.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

l. A connecting clip for electrical conductors, comprising a pair ofspring pressed jaws adapted to engage a binding post, one of the jawsbeing provided with an angular extension, a clamp formed of two memberscarried by the jaws and adapted to receive the bare end of an insulatedwire between them, and means mounted in the said angular extension andengaging the clamping members for closing them to clamp the wiretherebetween.

2. A connecting clip for electrical conductors, comprising a pair ofSpring-pressed jaws adapted to embrace a binding post, a pivotconnecting the shanks of the said jaws with each other, one of theshanks having a rearward extension provided with a ilange having athreaded aperture, a sectional clamp held en the saidjaiygtmand?A engaget-he bare end citan` insu- ,y lla ed cgi Aeter, yand a bolt screwing inthe said flange and engaging the said clamp to close or open the latter.

8. A connecting clip for electrical conductors, comprising a pair ofspring-pressed jaws adapted to embrace a binding post, a pivotconnecting the shanks 0f the said jaws with each other, one of theShanks having a rearward extension provided with a flange having athreaded aperture, a sectional elamp held on the said pivot and adaptedtoclampingly engage the bare end of an insulated conductor, and a boltscrewing in the said flange and engaging the said clamp to close or openthe latter, the said bolt having a bore for the passage of the said bareend.

4. A connecting clip for electrical conductors, comprising a pair ofjaws arranged one alongside the other and provided with Shanks havingheels overlying one the other, a pivot connecting the said heels witheach other, a Spring having its ends connected with the said shanks tomove the jaws toward each other, and a retaining member straddling bothShanks in a transverse direc-tion.

5. In combination, aninsulatedconduetor having a bare end, a pairwi'jaws having liilsshksf'and a pivot connecting the said shanks with eachother, one of the shanks having a rearward extension provided with a lughaving a threaded aperture, a spring having its ends connected with thesaid shanks to close the jaws, a clamp held on the said pivot andengaging the said bare end, and a bolt screwing in' the said threadedaperture and having a conical bore for the passage of the said bare endand for engaging the clamp to close the same on the bare end.

G. A connecting clip for electrical conductors, provided with anapertured inember, a sectional clamp` for engagement with the ofwaconductor, land a bolt screwing in the apertured member of the clip andprovided with a conical bore for the passage of the said bare end andfor receiving the free ends ot' the sections of the said clamp to movethe sections in clamping engagement with the said bare end.

In testimony whereof I have signed my name to this specification in thepresence oi' two subscribing witnesses.
